H-20 Series guns provide consistent bead deposition in high-flow, intermittent product assembly applications using high-viscosity hot melt adhesives and other filled thermoplastic materials.

• Improve service life with long-life cartridge design.
  
  
• Receive consistent performance and reliability with air-open spring-close actuation that exceed 3,000 cycles per minute.
  
  
• Choose from controlled-engagement single-orifice nozzles, precision multi-orifice nozzles or extended nozzle assemblies.
  
  
• Select from several configurations, including water-resistant design, integral-filtered bodies, nozzle extension assemblies, variable temperature controls and integral slot nozzles.
  
  
• Reduce service time with  interchangeable extrusion modules that are easy to clean and replace.

Standard Configuration

• Obtain high-flow versatility and comprehensive nozzle selection.

Large Ball-and-Seat (LBS) Gun

• Handle high-viscosity or filled materials using large bore fittings and a larger ball-and-seat. Ideal for drum melters, the H-20 LBS accommodates 5/16- and 5/8-inch hose diameters.

Micro-Adjust Gun

• Use for balancing flow rates when adjustment is critical for precise bead size.
  
  
• Adjust adhesive flow without changing hydraulic pressure.

Filtered Gun

• Remove char and contaminants that can inhibit flow and clog nozzles.
  
  
• Easily access filter for cleaning.
  
  
• Minimize downtime with high-capacity filtration that provides up to 10 times the service interval of in-line filters.
